TRACTION-WHEEL.

SPECIFICATION forming part of Letters Patent No. 372,426, dated November 1, 1887.

Application lled June l, 1887. Serial No. 239,95. (No model.)

To all whom, it may concern:

Beit known that I, AERIHIM MILLER, of Newark, in the county of Licking and State of Ohio, have invented certain Improvementsin Traction-Wheels, of which the following is a specification.

At the present day it is a common practice to employ ordinary farm-wagons to carry and actuate manure-sprezulers, seed-distributors, and similar mechanisms, which are mounted temporarily thereon and connected for the time being with one of the wheels.

It is the aim of my invention to provide means by which the wagon-wheel may be speedily converted into a good traction-wheel, adapted to take a firm hold on the ground and to operate the mechanism with acertainty and uniformity which cannot be secured when the wheel is used in its ordinary condition with a narrow tread and smooth face, and to admit of the wheel being quickly restored to its original condition when the Wagon is to be used in its ordinary capacity.

'Io this end the invention consists in ribbed or toothed segmental plates which are detachably secured to the wheel by bolts, as hereinafter more fully explained.

In the accompanying drawings, Figure 1 is a perspective view of a wheel provided with my attachment, one of the paris being shown detached. Fig. 2 is a perspective View, on a larger scale, of one of the rim-plates. Fig. 3 is a section through the rim of the wheel in the plane of its rotation. Fig. 4 is a transverse section through the wheel on the line of its axis and through the joint at the ends of the overlapping plates.

Referring to the drawings, A represents an ordinary wheelsuch as is at the present time in general use on farm-wagonswith a dat smooth tire, a, secured permanently thereon.

In carrying my invention into effect I pro' vide a series of segmental metallic plates, B, their inner faces being adapted to rit snugly upon the tire of the wheel, their form and number being such that when laid together end to end they will completely encircle the Wheel and form an outer or supplemental rim thereon. I form these supplemental plates The plates may be abutted end to end when A applied to the wheel and secured by separate bolts; but I prefer to form each plate with one end raised,as shown at c, sufcientlyto overlap the end of the next plate, this arrangement permitting a single bolt to be passed through the ends ot' the two plates for the purpose of holding them in position. Each plate is provided at the two ends, as shown, with perforations d and c, preferably elongated, to receive the fastening-bolts, which are passed through the plates and through holes in the tire and felly of the wheel to receive fastening-nutsfapplied to their inner ends. I prefer to employ for ordinary purposes fourteen plates for each wheel, and to locate the fastening-bolts between the spokes of the wheel. The fastening-bolts may be independent of the bolts commonly employed for holding the ordinary tire in position; or, it' made of Sullicient length, the one set of bolts may serve both purposes.

-My supplemental rim-plates may be made of the same width as the ordinary tire, or narrower; or they may be made as much wider as circumstances may demand, in order to overhang the -wheel on both sides, and thus give the same an increased tread or bearingsurface.

I am aware that traetiolrwheels have been variously constructed with ribs or lags on the periphery, and I lay no broad claim to this feature.

I am also aware that rubber blocks have been secured by clamping devices to the rim of a wheel; also, that a wheel has been conas shown, with a wooden felly and afiat metal tire thereon. In practice I iind that when the bolts for securing the supplemental platesvare passed through 'this wooden felly its elasticity prevents the parts from rattling loose, the

bolts and plates remaining invposition in a more satisfactory manner than would otherwise be the case. Y

Ordinary Wheels Vto' 4Which I apply my plates are commonly made,

1,. Asa newar'ticle of manufacture, a supplemental ri1n-platefor a Wheel, formed in one piece with the hollow lags and the perforated ends, one of Which is raised, as and for the purpose described. 25

2. The Wagon-wheel having the Wooden felly, the dat metal tire a,applied perma nently thereto, and the removable outer tire, b, consisting of the series of ribbed segmental sections secured by bolts passing therethrough 3o and through the tire and felly of the Wheel.

In testimony whereof I hereunto set my hand, this 25th day of May, 1887, iu the presence of two attesting Witnesses.
